Abstract

A device for separably coupling one end portion of a rigid or elastically deformable hose to a nipple has a first tubular element which is non-rotatably and sealingly secured to the one end portion of the hose, and a second tubular element which is rotatable on the first element and carries first detent members separably engageable with one or more second detent members on the nipple. Engagement of the first detent members with and/or their disengagement from the second detent member or members on the nipple merely necessitates rotation of the second tubular element relative to the nipple and relative to the first tubular element, i.e., the hose need not be twisted and/or otherwise deformed in order to couple it to, or to disengage it from, the nipple. A sealing ring is provided to automatically engage the first tubular element and the nipple when the first detent members are properly connected to the second detent member or members.
